I was installing coolant sensor and I guess I tightened it to far and it broke off, leaving the threads(brass)and the the sensor in the engine block.I'm freaked!I have easy out but I need to know precisely just what and how to get out of this mess. Has anyone ever removed this sensor before?It seems like it would be very difficult tapping into the wires,etc that are in the center of this component! please someone help!
